Abstract: A printing system includes a filter, a printhead including nozzles through which liquid is emitted, and a liquid supply system in liquid communication with the printhead through the filter. The filter, an electroformed metal structure, includes a plurality of first recesses, a plurality of second recesses, a plurality of first pores, and a plurality of second pores. Each of the plurality of first recesses includes a first recess diameter and a first recess center-to-center spacing relative to each other. Each of the plurality of second recesses includes a second recess diameter and a second recess center-to-center spacing relative to each other. Each of the plurality of first pores is in fluid communication with a corresponding one of the plurality of first recesses and each of the plurality of second pores is in fluid communication with a corresponding one of the plurality of second recesses.

Abstract: A mandrel, suitable for use when producing an electroform metal structure including, for example, a filter, includes a conductive material layer. A plurality of first photoresist pegs is located in a first area of the conductive material layer. Each of the plurality of first photoresist pegs includes a first diameter and a first center-to-center spacing relative to each other. A plurality of second photoresist pegs is located in a second area of the conductive material layer. Each of the plurality of second photoresist pegs includes a second diameter and a second center-to-center spacing. The first diameter is greater than the second diameter and the first center-to-center spacing is greater than the second center-to-center spacing.
